The Stadium: MMA Night

Walk out of the train, and head up the stairs towards the ticketing booth to trigger a cutscene. When that's done, exit the area using the green-lit doorway. As you exit, there will be two guards patrolling outside.

Follow the bushes around the yard and watch the guards. When they move away from the entrance, make your way inside. Use the Fast Walk option and keep moving to the west. Look for the Men's/Women's bathroom sign and walk into the Men's Room to the other side.

Exit the hall and make a right turn. Approach the green-lit door and exit outside. Duck under the metal door and climb over the railings. Jump above the small room and use the V-shaped bars to the other side. Jump over the window and back into the stadium.

Now walk upstairs and enter the large hallway. There is a guard patrolling the hall, so stay alert! The exit is located at the other end of the hall, so quietly follow the guard and then run past him and into the opened doorway to the VIP seating area. Take the metal catwalks and make your way to the other side to the other VIP area.

Exit the room to trigger a chase! Follow Cross as he runs outside the stadium to the garden area. Quickly get near him and choke him out!

Now exit the area and hightail it back to the train station downstairs to complete the mission.

ACHIEVEMENT/TROPHY UNLOCKED

But wait, there's something you need to do before going back to the Animus!

OPTIONAL OBJECTIVE: PLUGGING POWER SOURCE #2

Once the settings are back in the cave, proceed towards the southeastern stairway. As you approach the stairs, a cutscene with Juno occurs.

When that's done, continue making your way up the broken stairs to trigger another cutscene with Juno.

Now make your way to the top of the stairs. Follow the path to the other side to find a set of stairs going down. Jump down to the lowest floor to find a doorway. Head inside the door and climb up two sets of ledges to the top.

Approach the power control deck at the other end to trigger the opening of the cave for power source #3! Now that you've done all that, feel free to speak to everyone and then head back into the Animus to begin Sequence 9.
